Air Optix for Astigmatism are toric silicon hydrogel contact lenses that are meant for extended use. They are manufactured with the AQUA moisturising element, which links to the surface of the contact lens to establish a gentle and thin layer of moisture, thus allowing eyelids to slide freely and easily. The surface of the contact lens has a biologically compatible plasma component to reduce sediments. The back surface of the contact lenses is toric, and the lenses have two stabilisation zones to ensure sharp vision. When choosing these contact lenses, you will avoid signs of a lack of oxygen in the cornea, including dry eyes, redness, fogginess or an unpleasant feeling at day’s end.
